A company runs containerized image-processing applications on on-premises Kubernetes clusters that share a single NFS file store. The NFS capacity is exhausted and the company must migrate to AWS quickly. The Kubernetes clusters on AWS must be highly available. Which combination of steps will satisfy these requirements? (Choose two.)

Correct answer: Copy the NFS data to an Amazon Elastic File System (Amazon EFS) file system, and push the container images to Amazon Elastic Container Registry (Amazon ECR)., Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster to run the containers and mount an Amazon Elastic File System (Amazon EFS) file system on each node at the required path..
Why this is the answer
The correct combination involves migrating the NFS data to Amazon EFS and deploying the containers on Amazon EKS. Amazon EFS is a highly available, scalable, and shared file system service that is compatible with NFS, making it a direct replacement for the on-premises NFS store. Amazon ECR is the appropriate service for storing and managing container images in AWS. Amazon EKS provides a managed Kubernetes service for running containerized applications, ensuring high availability. Mounting Amazon EFS on EKS nodes allows the containers to access the shared file system, fulfilling the application's requirement for shared storage. Incorrect options: Using Amazon EBS is unsuitable because EBS volumes are block-level storage attached to a single EC2 instance and cannot be shared across multiple Kubernetes nodes simultaneously, which is required for an NFS replacement. Creating an Amazon ECS cluster instead of EKS would be a different orchestration platform, but the core issue of shared storage remains. While EKS is correct for orchestration, combining it with EBS for shared storage is still incorrect due to EBS's single-attach limitation.
